Passengers flying Southwest Airlines out of Milwaukee on Tuesday got quite a surprise when they saw who was checking them in at the ticket counter.

Milwaukee Brewers pitcher Yovani Gallardo and catcher Jonathan Lucroy made guest appearances at General Mitchell International Airport as part of a promotion of trading jobs.

Gallardo and Lucroy checked in passengers, helped load luggage on planes and even worked with Southwest employees on directing a plane into its parking spot near the terminal. The two players even brought along the team's Famous Racing Sausages to help in their efforts.

The appearances were part of Southwest Airlines expanded corporate sponsorship with the Brewers.
